# IO.sysread (from ruby core) --- ios.sysread(maxlen[, outbuf]) -> string --- Reads *maxlen* bytes from *ios* using a low-level read and returns them as a string. Do not mix with other methods that read from *ios* or you may get unpredictable results. If the optional *outbuf* argument is present, it must reference a String, which will receive the data. The *outbuf* will contain only the received data after the method call even if it is not empty at the beginning. Raises SystemCallError on error and EOFError at end of file. f = File.new("testfile") f.sysread(16) #=> "This is line one"
